A basic tester for measuring Cl / pH values in pool water. First measure the pool water values and, if they are not within the recommended range (pH 6.9–7.4; Cl 0.3–0.7), adjust the pool water using pool chemicals. First adjust the pH value (pH+ or pH-) and then adjust the chlorine level (only increase it - if the chlorine level is too high, do not lower it; it will decrease on its own in a few days). Chlorine should be added only after the pH has been regulated, because the effectiveness of chlorine drops rapidly outside the recommended pH range. The drop tester contains a set for measuring pH and a set for measuring the chlorine level in water. The pool tester is an indispensable helper if you want to ensure the proper functioning of the processes taking place in pool water. Testing should be carried out during the season every 7–14 days, depending on how heavily the pool is used, or whenever you suspect that the water quality is deteriorating.
